ABSTRACT:
A control system for a vehicle transmission prevents a vehicle from rolling backward on a slope, and includes a slope sensor for sensing the degree of a slope, a throttle position sensor for sensing position of a throttle valve, an engine RPM sensor for detecting RPM of the engine, a gear input speed sensor for sensing rotational speed of a transmission gear, a gear position sensor for sensing position of the transmission gear, a shift lever sensor for sensing operation of a shift lever, a CPU for reading signals from the sensors and outputting a control signal for keeping the clutch in partial engagement before starting an engine, an electric hydraulic pressure cylinder, and a clutch release cylinder mechanically joined to the electric hydraulic pressure cylinder for joining the clutch.
